Fibre optic cable EFB Elektronik O2561.0,5 0.5m SC Yellow

The EFB Elektronik O2561.0,5 is a 0.5 m SC–SC fibre optic cable (patchcord) designed for high-speed data transmission in structured cabling environments. It uses OS2 single-mode fibre with a 9 µm core diameter and yellow jacket for easy identification. The cable complies with common definitions of fibre jumpers as the shortest connection between passive interfaces and active device ports according to ISO/IEC 11801.

Advantages

This SC to SC fibre optic cable provides low attenuation and stable single-mode performance suitable for long-distance links. Its standardized connectors and single-mode OS2 fibre ensure predictable insertion loss and return loss characteristics. The yellow colour coding simplifies cable management in racks and patch panels.

Suitable for (tasks / use cases)

• Interconnecting equipment in data centres and telecom racks
• Patch panels and fibre distribution frames
• Short interconnect links between active devices and passive interfaces
• Laboratory measurements and equipment testing requiring SC–SC connectivity

How to use

Connect one SC connector to the device port and the other SC connector to the passive interface or patch panel port. Ensure connectors and ports are clean before mating to avoid signal loss or damage. Route the cable without sharp bends and avoid excessive tension to maintain optical performance.

Recommendations

For reliable performance, inspect and clean SC connectors with appropriate fibre cleaning tools before installation, keep bend radius above manufacturer recommendations, and store or label the yellow cable to reflect single-mode OS2 usage in your network documentation.
